PURPOSE: To evaluate the role of MRI in the management of cervical cancer treated by conventional four-field whole pelvic irradiation. METHOD AND MATERIAL: Between 1993-march and 1994-february, 20 patients(4 Stage I B, 3 Stage U A, 13 Stage U B) with invasive cervical cancer were eligible for evaluation of accuracy of conventionally designed lateral treatment field without MRI determination. RESULTS: 5 out of 20 Patients had inadequate margin without MRI. The position of uterine fundus was more important than cervix in correction of field size and the center of treatment field. CONCLUSION: This Preliminary date show MRI determination of uterine position prior to radiotherapy planning is essential in the case of four-field whole pelvic irradiation technique.

PURPOSE: Congenital hypothyroidism(CH) is not uncommon disorder, leading to retardation of mental development and growth, if not treated early. The aim of this study is to determine the factors influencing IQ of children with CH, diagnosed after 1 month of life. METHODS : Thirteen children with CH were included. They had intelligence test by KEDI-WISC(Korean Educational Development Institute-Wechsler Intelligence Scale for Children) and their medical records were reviewed. Their T4, TSH, height, age at diagnosis were investigated retrospectively. To evaluate the influence of T4, TSH, height, age at diagnosis on IQ, children were divided into three groups ; athyroid(n=8), sublingual(n=3), inborn errors of thyroid hormone synthesis(n=2) according to the result of thyroid scan. Results : In athyroid group, IQ closely correlated to VIQ and PIQ and had close relationship to T4 at diagnosis(.p=0.0086, r=0.8427), but no relation to TSH. There was no difference in height, T4 TSH, and IQ between athyroid and sublingual group. CONCLUSION : The results suggest that intellectual function in children with CH, diagnosed after 1 month of life depends on serum level of T4 at diagnosis. Further study is mandatory to elucidate the relationship between final IQ and factors, including thyroid function, age at diagnosis, adequacy of treatment, etc.

Effects of various peripheral vasoconstrictors on isolated porcine basilar and posterior communicating arteries(BA and PCA) were investingated and effected of flunarizine on the contractile responses were compared with those of a vasodilator, nitroglycerin. KCl elicited dose-dependent contractions in BA and PCA. 50mM KCl-induced contraction was not affected by nitroglycerin but dose-dependently inhibited by nimodipin and flunarizine in both rings. Epinephrine produced contractile response of BA and PCA in a dose-dependent fashion, but norepinephrine or phenylephrine did not cause obvious contraction by itself. Norepinephrine and phenylephrine elicited dose-dependent contractions in both rings treated with 10 -6M propranolol and the epinephrine-induced contractions were potentiated by pretreatment with propranolol, 5-hydroxytryptamine and histamine contracted BA and PCA in a dose-dependent manner and the contraction of PCA was more prominent than that of BA. In PCA rings, 10(-6)M 5-hydroxytryptamine and 10 -6M orepinephrine-induced contractions were not changed by nitroglycerin but inhibited by flunarizine in a dose-dependent manner. Small doses of flunarizine inhibited gradually both drug-induced contractions and large doses(3.5 x 10(-6) and 10(-6)M) steeply inhibit ed the contractions. Then the slopes of inhibitory curves in both cases were biphasic. Above results suggest that responsibility of catecholamine in porcine brain artery is more prominent in alpha-adrenoceptors than in beta-adrenoceptors, and inhibitory effect of flunarizine on brain artery results from inhibition of calcium influx through stimulated receptor-operated calcium channel(ROC) and potential-operated calcium channel(POC) .

Osteoporosis represents a reduced amount of bone tissue as compared with controls of same age and sex, and common feature of osteoporosis is a state of skeletal fragility leading to various fractures such as Colles' fracture, vertebral compression fracture, femur neck fracture, generally due to an inadequate amount of normally mineralized bone tissue, making the skeleton incapable of supporting normal mechanical demand. However it is difficult to quantify precisely its magnitude because of the variety of techniques used and the many bone sampling sites concerned. In 1970, Singh and associates(24.25) developed a method for grading the trabecular structure of the proximal end of the femur and reported that the femoral trabecular pattern index can clearly separate persons with osteoporosis from normal individuals. Cameron and its associstes developed an accurste method of determining bone mineral content by means of I-125 photon absorptiometry(5. 28). This method is consistently reproducible at the 98% level and has demonstrated agreement with ash measurement of cadaver bones at the 97% level. A comparative study of the usefulness of the femoral trabecular pattern index(Singh Index) and rsdial bone mineral content measurement by photon absorption was performed in 75 Kroean persons above forty years old. 25 of 75 persons were fracture patients due to osteoporosis. The results were as follows. 1. A significant difference in Singh index was noted between the fracture group snd control group. 2. A significant difference in bone mineral density was noted between the fracture group and control group. 3. A positive correlation was noted between the bone mineral denisty and Singh Index. 4. A significant difference in bone mineral density was noted between the fracture group and the control group which have same grade of Singh Index. So, we believe that bone mineral density is more objective and accurate than Singh Index. 5. We believe that both Singh Index and bone densitometer is useful in diagnosis and grading of osteoporosis.

OBJECTIVES: The goal of this study was to examine the association between zinc and lead level and symptoms of attention-deficit hyperactivity disorder (ADHD) among Korean children. METHODS: A total of 89 clinic-referred children participated in the study (ADHD group=45, control group=44). The participants were 5-15 years old, and were mainly from urban areas of Seoul, Korea. ADHD was diagnosed using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version. We excluded children with a comorbid psychiatric disorder, medical illness requiring medication, or a prior history of taking ADHD medication. In order to evaluate the severity of ADHD symptoms, parents' Korean ADHD Rating Scale (K-ARS) was used. The ADHD diagnostic system (ADS) was used for evaluation of the severity of inattention and impulsivity. All participants completed the intelligence test and hair mineral analysis. Multiple regression analysis was used to examine the effect of hair zinc and lead levels on the K-ARS and ADS. We measured the predictive ability of the zinc and lead levels using logistic regression analysis. RESULTS: The lead level explained the score for omission errors, commission errors, and response time SD in visual ADS in the ADHD group (adjusted R2=.243, p<.01, adjusted R2=.362, p<.01, and adjusted R2=.275, p<.01), the score for omission errors of auditory ADS in ADHD group (adjusted R2=.407, p<.01) and the entire group (adjusted R2=.292, p<.01). Zinc was significantly explanatory for the K-ARS scores for the entire group (adjusted R2=.248, p<.001) and the ADHD group (adjusted R2=.247, p<.05). CONCLUSION: These findings suggest a possible role of zinc and lead in ADHD. Lead concentration in hair samples affected the ADS scores, and this was more prominent in children with ADHD. Children with ADHD had a lower zinc concentration in their hair, and the zinc concentration in hair showed negative correlation with the K-ARS score.

OBJECTIVES: The principal aim of the present study was to investigate the characteristic depressive symptoms in patients with social anxiety disorder (SAD) and panic disorder in comparison to patients with depressive disorder. METHODS: This study included 132 patients with SAD, 128 panic disorder and 64 depressive disorder (major depressive disorder, dysthymia etc.) patients without comorbid psychiatric disorders. The Beck Depressive Inventory (BDI) is used to measure depressive symptoms. We divided BDI into three categories originally described by Shafer AB, including negative attitude toward self, performance impairment, and somatic symptoms. We compared the depressive symptoms of SAD, panic disorder and depressive disorder by using ANOVA. RESULTS: Negative attitude toward self was noticeable in SAD (SAD 0.54 +/- 0.23, panic disorder 0.41 +/- 0.17, depressive disorder 0.46 +/- 0.11, p < 0.001). Performance impairment and somatic symptoms were remarkable in panic disorder than in SAD and depressive disorder (performance impairment : SAD 0.39 +/- 0.21, panic disorder 0.44 +/- 0.14, depressive disorder 0.40 +/- 0.09, p = 0.009 ; somatic symptoms : SAD 0.07 +/- 0.10, panic disorder 0.15 +/- 0.12, depressive disorder 0.14 +/- 0.08, p < 0.001). CONCLUSIONS: The results facilitate an approach to optimal treatment for patients with comorbidity of anxiety disorder and depression.

OBJECTIVE: Social anxiety disorder (SAD) shows relatively delayed responses to pharmacotherapy when compared to other anxiety disorders. Therefore, more effective early therapeutic decisions can be made if the therapeutic response is predictable as early as possible. We studied whether the therapeutic response at 12 weeks is predictable based on the early improvement with escitalopram at 1 week. METHODS: The subjects were 28 outpatients diagnosed with SAD. The subjects took 10-20 mg/day of escitalopram. The results of the Liebowitz social anxiety scale (LSAS), Hamilton anxiety rating scale, and Montgomery-Asberg depression rating scale were evaluated at 0, 1, 4, 8, and 12 weeks of treatment. Early improvement was defined as a ≥10% reduction in the LSAS total at 1 week of treatment, and endpoint response was defined as a ≥35% reduction in the LSAS total score. The correlation between clinical characteristics and therapeutic responses was analyzed by simple linear regression. The correlation between early improvement responses and endpoint responses was analyzed by multivariate logistic regression analysis and receiver operating characteristic curves. RESULTS: When we adjusted the influence of a ≥35% reduction in the LSAS total endpoint score on a ≥10% reduction of the LSAS total score at 1 week of treatment for the patients' age, the early improvement group at 1 week of treatment was expected to show stronger endpoint responses compared to the group with no early improvement. CONCLUSION: The results suggest that a ≥10% reduction in the LSAS total score in a week can predict endpoint treatment response.

Meningioma has been considered to be rare as multiple growths. More often than not, they are associated with neurofibromatosis, bilateral acoustic tumors and multiple angiomata. Less frequently multiple meningiomas may be present without these associated problems. Cushing and Eisenhardt called the former "meningiomatosis" and the latter multiple meningiomas. The incidence of multiple meningiomas has been reported 1-8.9% of all intracranial meningiomas. The availability of CT has increased the incidence of the diagnosis of multiple meningiomas by visualizing smaller meningiomas which would have remained undetected and it seems to be reasonable that some elderly patients with multiple lesions diagnosed by CT should be followed and not operated on. We report a patient with multiple meningiomas without evidence of von Recklinghausen's disease and explore its various theories of the etiology.

A case of mucocele of the sphenoid sinus with blurred vision and headache is presented. Mucocele of the sphenoid sinus is relatively rare and benign. Accurate diagnosis is possible through Brain CT scan and MRI. But it should be included in the differential diagnosis of malignancy or pituitary tumor, and unnecessary treatment such as radiotherapy or craniotomy should not be performed. In this case, mucocele is extended into sella turcica which is markedly destroyed and eroded. We removed it by sublabial transseptal sphenoidal sinusotomy and drainage without difficulties and postoperative complications.
